Dr. Karen Becker explains that “Eradicating hormone-producing organs at a younger age disrupts the endocrine system, resulting in critical penalties like an elevated threat of aggressive cancers”.
Behavioral Points Linked to Hormonal Modifications
Elevated ranges of luteinizing hormone (LH) post-neutering can set off irritation within the mind, resulting in nervousness, worry, and even aggression. Dr. Jack Oliver from the College of Tennessee, notes that these hormonal imbalances could make canine extra reactive to emphasize and vulnerable to fear-based behaviors.[4]

The testicles and ovaries produce intercourse hormones, however your complete course of begins within the hypothalamus, deep throughout the mind.
The hypothalamus acts as a bridge between the mind and the endocrine system, translating sensory indicators (like a male smelling or seeing a feminine in warmth) into hormonal messages. It releases GnRH (gonadotropin-releasing hormone), prompting the pituitary gland to secrete luteinizing hormone (LH).
LH then stimulates the gonads to supply testosterone and estrogen. When hormone ranges drop, the pituitary senses this and releases extra LH, making a suggestions loop very similar to a bathroom tank refilling when the water is low and stopping when it’s full.

Protocols:
- For Males:

- Weekly testosterone injections (0.5 mg/kg subcutaneously)
- For Females:
- Suprelorin implant if LH is excessive
- Oral estrogen (estriol or diethylstilbesterol) as prescribed by your veterinarian

Advantages:
A overwhelming majority of canine expertise an total enchancment on the whole well being, larger mobility, decrease ranges of irritation, improved temper, coat high quality, and decrease charges of most cancers.

What’s Suprelorin (Deslorelin) and the way does it work?
The Suprelorin implant is a small, biocompatible gadget positioned just below the pores and skin, normally between the shoulder blades, by a veterinarian in a process much like microchipping that doesn’t require anesthesia. It comprises deslorelin, a GnRH agonist, which initially stimulates after which suppresses the manufacturing of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), resulting in a major drop in testosterone or estrogen and leading to non permanent infertility.
In intact canine, Suprelorin is used for reversible contraception, whereas in spayed or neutered canine, it helps scale back LH-driven irritation and might enhance well being points linked to hormone deficiency. The 4.7 mg implant lasts about six months and should be repeated for ongoing impact. Delicate swelling or itching on the website might happen, however critical unwanted effects are uncommon.
Suprelorin is accredited to be used in canine in almost 50 nations, together with the EU, UK, Australia, New Zealand, Canada, Mexico, and China.

What occurred to my canine and his progress on Hormone Alternative Remedy
At the age of 18 months, my lovely Border Collie, Pax, was a wholesome and robust canine.

His challenges prompted me to seek for solutions to his unexplained lameness, and finally, I got here throughout the analysis of Dr. Michelle Kutzler and Dr. Linda Brent and determined to start out Pax on the hormone alternative remedy protocol talked about above.[1][2]
His transformation has been extremely optimistic, much like canine within the analysis research.
Nearly instantly, Pax grew to become happier, had extra vitality, and slept much less in the course of the day. His coat has change into thicker, his mane is longer and extra pronounced. You may see what occurred within the earlier than and after video beneath.

It took about two months for him to get better from his lameness and accidents. I’m thrilled to report he’s been working, mountain climbing, and swimming as earlier than his process, and he’s pleased and injury-free.
He continues to get .2mg/kg of testosterone cypionate subcutaneously (injection underneath the pores and skin) weekly and can get a brand new implant as required (each six or twelve months) relying on the efficiency of Suprelorin I determine on.
Pax began his therapy in April 2024 and continues to thrive.
Here’s a video recorded a 12 months after he began his therapy. He’s pleased, robust and continues to be injury-free
